The scale on a highway construction drawing is 0.5 inches for every 45 miles. if the drawing shows the highway is 4 inches long, how long is the actual highway? miles

you can't solve x because it is 2 linear equation and you only have one equation

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
